Collection and habitat data.

This adventive Palaearctic species lives in both dry and wet habitats in the Palaearctic region, including meadows, fields, heaths, forests, and hilly steppe ( Hoebeke 1995). Adults occurred in decaying organic matter and compost, under stones, and among leaves. In New Brunswick, adults were collected from grass litter and drift material along river margins and from decaying gilled mushrooms and decaying (moldy) corncobs and cornhusks in mixed and hardwood forests. One individual was collected from wet moss on rocks adjacent to a waterfall. Adults become active very early in the season when a deep snow cover is still present, as a number of very active adults were collected from a sun-exposed bare patch of drift material on an upper river margin on 12 April when a 60-cm snow pack was still present. Adults were captured during April, May, June, and September.
